you think the US will team up with the aliens to control this planet ? :-)
The period 1946-47 was a long time ago and if aliens had been here since that time and the US government was secretly working in co-operation with these aliens, i would think the US military capability would be a lot more advanced by now. And, if the aliens have been on the US side, i don't think the Cold War with Russia would have lasted that long.
You mentioned that the reason the sightings have been more frequent in US, Russia, and Europe because of larger populations there. What about India and China ? Both countries have large populations and they are both geographically large as well. China has been a closed society, so may be such UFO sightings would have been classified as a "State Secret", but what about India ? Have there been much media reports in India of UFOs sightings ?
